Ubuntu – How to install rmagick on Ubuntu 10.04


Here's what I've done so far:

sudo apt-get install imagemagick libmagickcore-dev

This did not throw any errors, so I think that ImageMagick is installed fine. Then I tried installing the gem:

sudo gem install rmagick

This resulted in the following error:

ERROR:  Error installing rmagick:
    ERROR: Failed to build gem native extension.

Can't install RMagick 2.13.1. Can't find MagickWand.h.

What do I need to do to install rmagick on Ubuntu 10.04?

I think you also have to install libmagickwand-dev from the ubuntu archive:

sudo apt-get install libmagickwand-dev

This package contains the MagickWand.h file.
